Bottom Line: These aggregate into supra-molecular layers oriented parallel to the ac plane by C-H⋯O inter-actions.These layers then stack in an ABCD pattern along the b-axis direction by additional C-H⋯O inter-actions to give the full three-dimensional crystal structure.The central chain in the di-pyridyl-amide molecule has an anti-gauche conformation.

ABSTRACT
In the crystal structure of the title co-crystal, C25H32N4O2·C8H6O4, isophthalic acid and [propane-1,3-diylbis(piperidine-4,1-di-yl)]bis-(pyridin-4-yl-methanone) mol-ecules are connected into supra-molecular chains aligned along the c axis by O-H⋯N hydrogen bonding. These aggregate into supra-molecular layers oriented parallel to the ac plane by C-H⋯O inter-actions. These layers then stack in an ABCD pattern along the b-axis direction by additional C-H⋯O inter-actions to give the full three-dimensional crystal structure. The central chain in the di-pyridyl-amide molecule has an anti-gauche conformation.

Mentions: The chains aggregate into supra­molecular layers (Fig. 3 ▶) oriented parallel to the ac plane by C—H⋯O inter­actions between ppbp pyridyl C atoms in one chain, and ppbp carbonyl O atoms in another chain [C⋯O distances = 3.119 (3) and 3.122 (3) Å]. These layers then stack in an ABCD pattern along the b-axis direction to give the full three-dimensional crystal structure of the title co-crystal (Fig. 4 ▶). Supra­molecular C—H⋯O inter­actions [C⋯O distance = 3.066 (3) Å] between ppbp pyridyl C atoms in one layer motif, and ppbp carbonyl O atoms in another layer motif provide the impetus for the stacking of layers.
